The keyword for the success of any online video is "submitting" video to
www.coalindia.org . The main advantages are that your videos will be hosted for free and they will not take up any cost.
Share your videos. If you really want to make yourself known, allow users to be able to link to your videos. Viral marketing videos are the best way to make companies (and, subsequently, their products/services) known across quite vast Internet user communities. They carry a company's name across the Web at far greater speeds than any other marketing tool in existence.
Don't forget to use "Tell a friend" or "friend Inviter" at the end of your video.
